Work and energy

1. The problem statement, all variables and given/known data
A body moves a distance of 10 meter along a straight line under the action of a force of 5 newtons. If work done is 25 joules, the angle which the force takes with the direction of motion of the body is:
a: 0 degree
b: 30 degree
c: 60 degree
d: 90 degree

2. Relevant equations
work=fdcostheta

3. The attempt at a solution
what formula should we use to get the degree or how to figure out it by making a picture?

Based on the work's definition, to be honest, the more precise version of what you wrote in the Relevant equations, you have to find ##F\cdot d,## since the force is a constant vector here. Hence by what you had, you can get ##W=F\cdot d=|F||d|\cos\theta,## which can lead you to what you want.
